CAR-BRAKE.

SPECIFICATION forming part of Letters PatentA No.v 355,505, dated January 4,1867. I

Application tiled October 26, 1886. Serial No. 217,230. (No model.)

To all whom-it may concern:

Be it known that we, MANDY T. CARSON and JAMES D. GURGANUs, of Whistler, in the county of Mobile and State of Alabama, have invented a new and Improved Car-Brake, of which the following is a full, clear, and exact description.

Our invention relates to car-brakes, and has for its object to provide simple, inexpensive,

j and readily-adjustable attachments to a carbody and brake-staff which will allow said staff and attachments to be lowered beneath the plane of the top of the car, to permit easy loading of lumber, car-wheels, railroad-iron, or other heavy cumbersome freight on the car, and will allow the stati to be raised again quickly to operative position.

The invention consists in certain novel features of construction and combinations of parts of the car-brake and its connections to the car-l body, all ashereinafter fully described and claimed. v

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the gures.

Figure 1 is an end view of part of the end of a platform-car with my improved brake connected thereto and the staff indicated in lowered position in dotted lines. Fig. 2 is a vertical sectional elevation ofthe foot of the erect car-brake staff and its connections with the car. Fig. 3 is a detail plan view with the brake staff in horizontal section; and Fig. 4 is a detail vertical sectional view of the brakestaff rest and adjacent part of the car.

The brake-staff A, at its lower end, is fitted to slide in projecting lugs b b of a cast-metal block, B, which is pivoted to turn transversely of the car platformor body C on a cast-metal plateD, which is fixed by bolts d d to the end sill ot the car. The block B is connected to the plate D, preferably by the entrance of a boss, d', on said plate into a correspondingly-shaped hole in the block, and outside of this boss there is placed on the bolt d, beneath its head, a washer, b', which overlaps the outer face of the block B and holdsv it quite snugly, but so as to turn freely on the boss d as a center.

Directly under the lugs b b of the block B the main plate D is provided with upper and revolnble socket E, which has a square or fiat sidedapertnre, e, in its upper end, and into which the correspondiugly-shaped .lower end, a, of the brake-staff A is adapted to tit, to cause the socket to turn as the brake-staff is turned. An eyebolt, F, passed through the socket E below the 'lower lng d2 of the plate D, prevents lifting of the socket from its bearings and affords a means for attaching the brake-chain to the socket, and whereby, when the socket is turned by the brakestaff, the chain (not shown) may be wound onto the socket for applying the brakes to the wheelsof the car, and may be unwound, for releasing the brakes, in a well` known manner.

In the brake-staff A, between the lugs b b of the block B, there is fixed a pin, G, which by contact with the upperlug,b,will prevent disconnection of the staff from the block when the end ct of the staff is withdrawn from t-he brake-chain socket E, as will be understood from Fig. 2 of thedrawings, which also shows the socket E made hollow, which not .only

relieves the socket of unnecessary weight and makes it stronger, but insures constant clearance of dust from its aperture e, to which the brake-staff is adapted, thus allowing the staff to be lowered fully when it is swung up to the vertical position, at which time the block B will strike a lng or stop,.H, on the main plate D, to hold the end ct oi' the staff' directly over the socket-aperture c and insure instant engagement of the staff and socket when the sta is lowered, as shown in Fig. 1 of the drawings. i

To the transverse car-sill or end beam there is fixed a bracket, l, having a half-round notch, ft', into which the staff A falls or rests when the staff is lowered, as shown in dotted lines in Figs. 1 and 3. I prefer to make the bracket yI with a dowel, J, which enters a hole in the car-beam, thus allowing secure attachment of the bracket, so that it cannot swing out of proper position, by a single holt, K, passed through -the bracket and car-beam( (Sec Fig. 4. of the drawings.)

To a lateral-lug, b2, on the pivoted block B there is pivoted a dog, L, whichA may be engaged with a ratchet-wheel, M, fixed to the brake-staff A, to hold the brakes applied to lower lugs, d2 d2, in which is fitted looselythe ICO the car-wheels in the usual way, and the staff I which socket the end of' the staff is adapted,

will be long enough to allow it to be operated conveniently from the car-platform by turning its hand-wheel A, which will stand at the side of the car when the brake-staff is lowered.

The operation of the brake is very simple and effective, as follows: We will suppose the brake-staff is in the vertical operativ-'e position shown in full lines in Fig. l, with the sta'A engaged with the brake-chain socket and drum E. Should it be desired to lower the staff, so as to leave the entire surface of the car-platform unobstructed all around,to allow lumber or machinery or car-wheels or railroad-iron to be loaded or unloaded conveniently, it is only necessary to lift the staff Aa couple ofinches, or until the pin G strikes the upper lug,I b, of the block B. The staff then will be withdrawn from the brake-chain socket E, as in Fig. 2, and the stafin then may be let fall or may be lowered into the notch i of the bracket I, and every part of the brake w'ill be below the plane of the top of the car, as will be understood from the dotted lines in Fig. 1 of the drawings. After loading the car, the brake-staff will be swung up again until the pivoted block B strikes the stop H, and the sta-ff may then be lowered into the socket E, into operative position for applying or releasing the brake.

It will be noticed that there are no small parts of or attachments to the brake to get out of order or be lost, which is an important consideration in repairs as well as in rst cost, and the brake-staff cannot be unshipped from the pivoted block nor the block from the main plate; hence the brake may always be operated with safety by the most inexperienced persons, and this last feature of the brake will be more apparent when it is considered that there are no bolts, pins, catches, or chained-up attachments to be unloosed or removed prior.

to operating the brake, which thus is as nearly automatic as it is possible for such contrivances to be made for practical use.

Having thus fully described our invention, what we claim as new,and desire to secure by Letters Patent, is-

1. In a car-brake, the combination, with a car body or platform, of a block, B, pivoted thereto, a staff, A, fitted for limited endwise movement and for rotation in the blockB, and a socket, as E, carrying the brake-chain and held revolubly to the car-body, and to substantially as described, for the purposes setf'orth. p 4

2. In a car-brake, the combination, with a car body or platform, of a block, B, pivoted thereto, a staff, A, fitted for limited endwise movement and for rotation in the block B, a socket, as E, carrying the brake-chain andheld revolubly to the car-body and to which the end of the staff is adapted for mutual movement, and a stop, as H, limiting the swinging movement of the staffwhen it is in position to engage the socket, substantially as described, and for the purposes set forth. n
